My guess is we won't have just a binary before AGI/after AGI situation.
I would think that there will be a period of development before AGIs
take off in the classic sense and start developing 'magical powers' that
enable then to leave the Earth at their own volition. So multiple
operating AGIs before that point will be likely and useful.

But *if* part of friendliness is an urge for company then when an AGI
gets the chance to row off into the wild blue yonder they might take a
friend or two (original or cloned).

Anyway AGIs never need to be alone so long as they can make/access
hardware - they can always clone themselves - perhaps with useful
variations so that they are not just talking to themselves.
